Hi...I can't really believe I am answering this..so unlike me but your Dad sounds nice and fun. I've got about 100 days cruising and most of them have been solo. I've met a lot of people who have become friends but the cost penalty traveling alone is limiting. I just returned from a 24 day Holland America Caribbean cruise. I went with a gal that I met on a cruise in New Zealand and we traveled famously together. I'm 63 and she is 49. I'm new to this site but would not mind chatting or emailing privately.
